1895 Gomphus adelplius Calvert, N. Y. ent. soc. Jour. 3 : 45 (listed from 



Bethlehem) 

 1897 Gomphus adelphus Calvert, N. Y. ent. soc. Jour. 5:93 (listed from 

 Kenwood) 



The specimens above described and listed were collected in New 

 York state by Drs Fitch and Lintner. The species is also known from 

 Massachusetts. I have not met with it in either immature or adult 

 stage, and know nothing of its habitat or habits. 



Dr Hagen has carefully described a nymph from Cambridge Mass., 

 referable by supposition to this species in the Trans. Am. ent. soc. 1885, 

 12 : 262. If the nymph be full grown, as he thought, there can be but 

 little doubt that it belongs to this species. However, his description 

 agrees in every point excepting size with G. fraternus bred by me in 

 Illinois. Unfortunately I did not get time while in Cambridge for the 

 comparison of my own nymphs with Hagen's types. I have stated the 

 difference in size in the foregoing table. These being all the differences 

 known to me, I have nothing farther to add concerning this species.

This species is abroad during the first two weeks of June. It has not 

 hitherto been reported from New York state, but I have seen a specimen 

 collected near Ithaca. The nymph is unknown. I have not seen the 

 imago alive. Prof. Kellicott wrote of it, " It rests on rocks projecting 

 from rapids, or on the banks near by the most rapid parts of streams."

This species is quite abundant at Ithaca, and has not as yet been 

 reported from any other locaHty. It flies during the latter part of May 

 and the first week of June. I found a meadow beside a patch of woods
